Custom degasser improves precision in polymer viscosity analysis Biotech Fluidics AB has collaborated with Spanish polymer analysis specialist Polymer Char to integrate a customised DeGASi®


Polymer Char’s Intrinsic Viscosity analysers - optimising reliability and data quality for polymer characterisation.


In viscometric analysis, particularly relative viscometry, the presence of dissolved gases such as oxygen and carbon dioxide in high-purity solvents can lead to microbubble formation during temperature shifts or flow changes. These bubbles can destabilise detector signals and introduce pressure variations, compromising the accuracy and reproducibility of viscosity measurements.


By incorporating an optimised degasser, these risks are significantly reduced. The degasser continuously removes dissolved gases from the solvent stream, improving flow consistency and enhancing signal stability - both essential for robust analytical performance.


Alba Cárdenas, Intrinsic Viscosity product expert at Polymer Char, explained:“We turned to Biotech Fluidics for their deep expertise in degassing and their openness to customisation. The result is a degasser that fits seamlessly into our systems, delivering smoother flow and better signal-to- noise ratios, which are crucial for achieving high-quality, repeatable results.”

Advanced GC with CO2


reduction visualisation


Shimadzu has announced an important update for its compact Brevis GC-2050 gas chromatograph, adding a host of new features that significantly broaden its application scope. This latest development transforms the system into a fully equipped, flexible solution capable of supporting an even wider range of industries - with particular focus on the growing demands of the Green Transformation (GX) sector.


A standout addition is the introduction of the world’s first CO2 meaningful insights into their sustainability performance.


To meet the increasing need for precise and efficient gas analysis in areas such as green energy development and process control, Shimadzu has enhanced its Automatic Gas Analysis System. This now pairs an improved Thermal Conductivity Detector (TCD) with the Auto Gas Injector GI-30, delivering superior sensitivity in a compact format.


Further extending the system’s versatility, the Brevis GC-2050 can be configured with a range of compatible accessories. These include the Jetanizer/Polyarc microreactor system for sensitive, easy quantification using a universal FID detector, and a customised GC setup featuring the VB-30 Series valve box for petrochemical and gas manufacturing applications. Other options include the TD-30 thermal desorption system for precise atmospheric VOC analysis, the PY- 3030D pyrolysis furnace for resin and additive characterisation, and the HS-20 NX headspace sampler for analysing volatile compounds in both liquids and solids. Additionally, a multi-detector configuration can be assembled using Advanced Flow Technology for simultaneous compound detection.


Originally launched in 2023, the Brevis GC-2050 continues to build on Shimadzu’s reputation for compact, high-performance gas chromatography systems. These new enhancements enable laboratories to access a complete, modular GC platform designed to deliver precise results, reduce environmental impact, and save valuable bench space.

Premium mobile phase inlet filters


These high-quality filters, made from stainless steel or polyethylene and fitted with PEEK tubing connectors, are designed to enhance the performance and longevity of High-Performance Liquid Chromatography (HPLC) systems. By effectively removing particulates and contaminants from solvents, they help protect instruments and ensure reliable analytical results.


Manufactured from high-purity sintered stainless steel or porous polyethylene, the filters deliver superior filtration to maintain solvent cleanliness and prevent blockages. This contributes directly to the integrity and reproducibility of chromatographic data.


The white colour of the polyethylene ‘stones’ makes it easy to detect dirt or particulate build-up at a glance, enabling users to schedule timely maintenance and avoid unexpected interruptions.


Each filter features a versatile ‘Tripod’ connector that supports easy attachment to 1/8th or 1/16th tubing. This flexibility makes them suitable for a wide range of applications across different HPLC setups.


In addition to their excellent chemical resistance, the passivated stainless-steel filters are both economical and durable - offering a cost-effective alternative to filters from instrument manufacturers without compromising on quality.


Designed for simplicity, the filters are quick to install and easy to maintain. This ensures reliable protection for HPLC columns and instruments, contributing to longer equipment life and consistent system performance.


By incorporating Microsolv’s Polyethylene & Stainless Steel Mobile Phase Inlet Filters into your solvent bottles, you can significantly reduce the risk of pump and valve wear, extend the lifespan of your columns, and ensure consistent, high-quality chromatographic performance.
